Raptor Technology Group designs and develops modularized biodiesel production systems designed to manufacture relatively small quantities of biodiesel using multiple, high free fatty acid ("FFA") feedstock. Raptor facilities are regarded by many as some of the most modern and highest quality biodiesel operations in the US.

The Raptor flagship system is designed for the production of 3.6 million gallons of biodiesel annually. Raptor designs and fabricates these modularized systems for the processing of higher FFA feedstock at rates considered "small" by traditional industry standards. The system is based on practical, hands-on operation and is designed to enable the producer to process the higher FFA feedstock in a cost-effective manner. The oil-rich seed crop feedstock produced by Eco Growers Group will be mixed with the yellow grease currently being processed to create this newly diversified biodiesel.

Raptor provides technology based on process innovations and an array of clean technologies that are designed to favorably impact company production by helping to use natural resources more efficiently. Their biodiesel production systems are designed around biodiesel process technologies that leverage innovative process intensification techniques to accelerate and enhance traditional biodiesel reaction kinetics, thus decreasing process time, reducing energy and raw material needs, and increasing product quality. These benefits translate to increased capital and operating cost efficiencies at smaller scales as compared to traditional biodiesel process technologies.

Initially, the biodiesel plants will be producing biodiesel from yellow grease, the oil in restaurant deep fryers that must be changed periodically. Yellow grease is an excellent and abundant source of biodiesel feedstock, however the prices have become volatile as oil and food commodity prices fluctuate. Virgin vegetable oils are used by some US biodiesel producers, though it is often considered a high cost feedstock.
